Hello to every body
I'm using the gnuradio application uhd_fft (py) to analyse fft spectrum in real time. Unfortunately maximum length (fft-size) is 4096 samples which result in a low resolution frequency in my application (center frequency 5GHz).
If I try to lunch uhd_fft with the option –fft-size greater than 4096 a segmentation fault happens
Would anybody suggest me how to increase the length of the fft? I’ve checked the script of uhd_fft.py and fftsink2 but I could not find anything related with fft vector size.
Thank you very much,
